That is not really accurate. The young people get older as well. And change their world view. Once you hear hundreds of times the "bad" news of immigrants, workers from rumania taking your jobs, etc, experiencing the slowness of evolvement of the EU or just switch to thinking british style (nations do better, europe is only a shared market). For sure, that is all inaccurate in one way or the other, but people are busy or in bad situations, leaving their enthusiasm behind them.
